NON-CONDUCTING HANDLE.

SPECIFICATION formingpart of- Letters Patent No. 756,401, dated April 5,1904.

Application filed November 17, 1902. Serial No. 131,691. (No model.)

To all 111720771 it may concern.-

Be it known that I, CLARENCE M. PERKINs, a citizen of the United States,and a resident of the city of St. Louis and State of Missouri, haveinvented a new and useful Improvement in Non-Conducting Handles, ofwhich the following is a specification.

It has heretofore been customary to insulate the handles of silverteapots and similar vessels by inserting horn or ivory or other similarmaterial between the handle proper and the parts to which it isattached. Usually the horn is a cylindrical piece with its diameterreduced at each end, one end being inserted into the hollow baseprovided therefor on the body of the vessel and the other end beinginserted into the hollow handle, so that the central shoulder intervenesbetween the metallic parts. Under this arrangement the pieces of hornmust be of considerable size and strength and the fastening is liable towork loose and allow the handle to wabble.

It is the principal object of my invention to economize horn, to provideagainst the working loose of the handle, and to provide for thetightening of the handle in case it should become loose.

To these ends my invention consists in mounting an insulated bolt in thebase portion of the handle in position to Work into a nut providedtherefor in the handle proper and in equipping the bolt with aninsulatingbutton having a polygonal hole arranged to fit over apolygonal section of the bolt, so as to constitute a means for turningthe bolt.

My invention also consists in the combination and arrangement of partshereinafter described and claimed.

In the accompanying drawings, which form partof this specification, andwherein like symbols refer to like parts wherever they occur, Figure lis a side view of a teapot with the parts constituting the means formounting the handle shown in section. Fig. 2 is a detail view of thebolt. Fig. 3 is a detail View of the insulating-button. Fig. 1 is asectional detail of the stiffening-thimble and the insulating-sleevetherein.

The handle proper, 1, of my device is hollow or tubular, and preferablythe ends thereof soldered to the pot.

are turned inwardly to constitute stiffeningflanges 2. Inside of thehandle near each end is mounted a threaded nut 3, adapted to receive thethreaded end of a bolt 4, which is mounted in the base member 5 andprojects therefrom. The base member 5 is likewise tubular and has oneend adapted to be soldered onto the body 6 of the pot, While its otherend has an annular flange 7 for the purpose of stiffening it. Inside ofthebase member is a thimble or sleeve 8, which at one end is secured tothe annular flange and has its free end 9 flanged to increase itsrigidity and afford a large bearing-surface for the bolt-head 10. Thisbearing-surface forms a shoulder for engaging the bolt-head 10. The boltextends through the thimble or sleeve 8 and is surrounded by a sleeve orcoating 11, of insulating material, which intervenes between the thimbleand the body and head of said bolt. The intermediate portion of the bolthas a rectangular or polygonal section 12, slightly larger in diameterthan that of the threaded end portion of the bolt. A button ofinsulating material 13, such as horn or vegetable ivory, has a centralhole 14 of a shape and size to fit over the polygonal portion of thebolt and is of slightly larger diameter than that of the end of thehandle proper.

The construction hereinbefore described is mounted and used as follows:The bolt is inserted through the open bottom of the base member of thehandle and through the sleeve or thimble therein before the base memberis The button is fitted over the polygonal portion of the bolt, and thenthe handle proper is brought into position for the threaded end of thebolt to enter the nut. The button is then turned by hand, causing thebolt to screw into the nut and draw the parts tightly together. In thisposition the button separates theprincipal metallic parts, and thesleeve or coating of insulating material around the bolt completelyinsulates said bolt. On

account of the long bearing furnished by the thimble the handle is heldrigidly and its liability to loosen is reduced, and in case the handleshould become loose it is easily tightened by merely turning the button.

Obviously the button may be made of any terial intervening between thebolt and the thimble and a button on said bolt between the handle properand the base portion.

2. A heat-insulating handle consisting of a handle proper having a-nutfixed therein, a hollow base and a bolt swiveled in said hollow base andarranged to cooperate with said nut,

and a button of insulating material between said handle proper and saidbase, said button fitting over a polygonal section of said bolt wherebyit is adapted to turn the same, substantially as described. I

3. A non-conducting handle consisting of a handle proper having a nutfixed therein, a hollow base consisting of a metal shell flanged atoneend and adapted to be mounted at its other end upon the body of thevessel, a thimble inside of said shell and fixed to its end flange, anda bolt extending through said thimble and having a threaded nut workingon its end, a sleeve of insulating material intervening between saidthimble and the head and body of the bolt, and a button of insulatingmaterial mounted on said bolt and lying between the base and the end ofthe handle proper, substantially as described.

4. The combination with a pot or vessel, of a heat-insulatinghandleconsisting of a handle proper having nuts fixed therein, hollow baseportions mounted upon the body of said vessel and having their outerends flanged, insulated bolts swiveled in said bases and arranged tocooperate with said nuts, and a button of insulating material betweeneach end of the handle proper and the adjacent base portion, each ofsaid buttons having a hole fitting over a polygonal section of thecorresponding bolt whereby it is adapted to turn the same, substantiallyas described.

5. Anon-conducting handle comprising a handle proper, a base portionprovided with an inner shoulder, a bolt having one end engaging theshoulder'and the other connected to the handle proper, heat-insulatingmeans between the bolt and the base portion, and a flat button ofheat-insulating material lying between the base portion and the end ofthe handle proper.

6. A non-conducting handle comprising a handle proper and ahollow baseportion, said base portion being provided with an inner shoulder, aheaded bolt having its head engaged with the shoulder and its oppositeend secured to the handle, and a button of heatinsulating materialmounted upon the bolt between the handle proper and the base portion andadapted to manipulate the bolt.

7 A non-conducting handle comprising a handle proper, a base portionprovided with an internal bore and an inner shoulder, abolt having oneend engaged with the shoulder and the other end connected to the end ofthe handle proper, a button. of heat-insulating material surrounding thebolt and lying between the end of the handle and base portion; andheat-insulating material between the bolt and the shoulder and the innerwall of the bore.
